How to Install Accordion Blinds: A Step-by-Step Guide for a Flawless Fit

Accordion blinds—also known as cellular or honeycomb shades—are a masterclass in combining form and function. With their crisp, uniform pleats and superior insulation properties, they are a staple for anyone looking to achieve a clean, modern aesthetic.

While the idea of installing window treatments yourself might seem daunting, achieving a professional-grade finish is remarkably straightforward. At LazBlinds, we advocate for the inside mount installation method. By mounting the blinds entirely within the window frame, you eliminate bulky hardware on your walls, maintain clean architectural lines, and create generous macro whitespace around the window.

Here is exactly how to install your new accordion blinds for a flawless, integrated look.

Before You Begin: The Tool Checklist

For a standard inside-mount installation, you will only need a few basic tools:

• A steel measuring tape
• A pencil
• A cordless drill (with a small drill bit for pilot holes)
• A Phillips-head screwdriver

The Installation Process

Proper alignment is the secret to a seamless installation. Follow these steps carefully to ensure your blinds operate smoothly and sit perfectly flush within the frame.

1.Mark the Bracket Placement:Measure twice to ensure perfectly level blinds..

Position your installation brackets inside the top corner of the window frame. Using your pencil, mark the exact spots where the screws will go. Ensure the brackets are set deep enough so that the front of the blind will sit completely flush with the wall once installed.

2.Drill the Pilot Holes:

Using a small drill bit, carefully drill shallow pilot holes over your pencil marks. This prevents the wood or drywall of your window frame from cracking when you drive the screws in.

3.Secure the Brackets:

Place the brackets back over the pilot holes. Using your screwdriver or drill, drive the provided screws through the brackets and into the frame until they are completely tight and secure.

4.Mount the Headrail:Listen for the snap to ensure it is locked..

Lift your accordion blind and hook the front edge of the headrail into the front lip of the brackets. Gently push the headrail backward and upward until you hear a distinct “click”—this means the blind is securely locked into the bracket system.

5.Test the Mechanism:

Gently pull the blind down and push it back up to test the operation. It should glide smoothly. If you are using a Light Filtering fabric, this is the perfect time to step back and admire how the crisp pleats diffuse the sunlight.

Why We Always Recommend the Inside Mount

When customizing your order, always measure for an inside mount if your window depth allows it.

Hanging window treatments outside the frame can cast unwanted shadows on your walls and make the space feel cluttered. An inside mount ensures the blind becomes a built-in architectural feature rather than a decorative add-on. It reinforces a monochromatic, quiet luxury aesthetic by keeping the focus entirely on the soft, filtered light rather than the mounting hardware.
